SPARK-ARRESTER.

SPECIFICATION forming part of Letters Patent No. 225,572, dated March 16, 1880. l 1 Application filed December 24, 1879.

To all whom it may concern:

construction and arrangement of a spark-an roster for locomotives, as'will be hereinafter more fully set forth.

In order to enable others skilled in the art to which my invention appertains to make and use the same, I will now proceed to describe its construction and operation, referring to the annexed drawings, in which Figure l is a side elevation of my invention. Fig. 2 is a horizontal section, and Fig. 3 a longitudinal vertical section, of the same. Fig. 4

I is a vertical section, showing a modification of the invention.

A represents the boiler, 13 the smoke-stack, and G the cab, of alocomotive. On top of the stack B is a hood D, provided with an open- I ing at the front with a funnel-shaped extension, E. At the top of the hood D, directly above the stack, is an opening, with a valve, F, to be operated by the engineer from the cab of the engine. l

The valve F is to be open when the locomotive stands still, so that the smoke, &c., will pass upward and out;'but when the 1ocomotive is in motion the valve F is to be closed, and the air then rushing in at E will carry the smoke and cinders backward through a passage, H, into a tank, G, located on top of the cab O. This tank is to contain water or other liquid to a suitable depth, and is provided with a series of deflectors, I 1 1 as shown in Fig. 3. The smoke and cinders pass down over the first deflector, I, the'cinders dropping down into the water, while the smoke continues up anddown over the other deflectors, and becomes more or less condensed by contact with the water. The remainder of the smoke passes out at the upwardlycurved rear end, J, of the tank, but here it is also retarded by a curved deflector, I so as to insure the perfect separation of all the cinders, which are thus deposited in the water.

To insure the perfect distribution of the smoke and cinders over the entire surface of the Water a series of wings or. partitions, a, are arranged in the forward end of the tank G, as shown in Fig. 2. On each side of the tank is a hopper-outlet, L, into which the cinders are scraped by means of a scraper, K, when desired to clean, them out,they passing then downward to the side of the track through a pipe, M. In the upper end of each pipe M, or in the outlet L, is a valve, b, which is only to be opened when desired to clean out the cinders. N is an overflow-pipe leading from the tank into the pipe M below the valve 1), so that all water above a certain height will pass out.

In Fig. 4 I have shown a modification of the invention, in which the tank is located directly behind the smoke-stack and the hood curves.

downward into said tank. An outlet-pipe extends on each side of the boiler, and a valve is arranged to be opened when cleaning the same, as above described.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

l. The hood D on top of the smoke-stack, and provided with front inlet, E, and top valve, F, and connected with a tank, G, containing liquid, all constructed and arranged substantially as and for the purposes set forth.

2. In a sparkarrester, the tank G, connected with the hood D on top of the smoke-stack, and provided with a series of deflectors, I I 1 850., all constructed and arranged substantially as and for the purposes herein set forth.

3. In a spark-arrester, the wings or partitions at in the tank G, constructed and arranged as shown, for the purposes set forth.

4. The automatic overflow-pipe N, in combination with the tank G, pipe M, and valve 1), all constructed as and for the purposes set forth.

In testimony that I claim the foregoing I have hereunto set my hand this 24th day of November, 1879.

GEO. B. F. COOPER.
